WAGO-I/O-SYSTEM 750
®
750-644 Bluetooth RF-Transceiver
- I/O modules 750-440, 750-609 and 750-611 must be installed in an IP 64
minimum enclosure.
- I/O module 750-540 must be installed in an IP 64 minimum enclosure for
230 V AC applications.
- I/O module 750-440 may be used up to max. 120 V AC.
When used in the presence of combustible dust, all devices and the enclosure shall
be fully tested and assessed in compliance with the requirements of IEC 61241-
0:2004 and IEC 61241-1:2004.
When used in mining applications the equipment shall be installed in a suitable
enclosure according to EN 60079-0:2006 and EN 60079-1:2007.
I/O modules fieldbus plugs or fuses may only be installed, added, removed or
replaced when the system and field supply is switched off or the area exhibits no
explosive atmosphere.
DIP switches, coding switches and potentiometers that are connected to the I/O
module may only be operated if an explosive atmosphere can be ruled out.
I/O module 750-642 may only be used in conjunction with antenna 758-910 with
a max. cable length of 2.5 m.
To exceed the rated voltage no more than 40%, the supply connections must have
transient protection.
The permissible ambient temperature range is 0 °C to +55 °C.

11.2.2 Special conditions for safe use (ATEX Certificate TÜV 07
ATEX 554086 X)
1. For use as Gc- or Dc-apparatus (in zone 2 or 22) the Field bus Independent
I/O Modules WAGO-I/O-SYSTEM 750-*** shall be erected in an
enclosure that fulfils the requirements of the applicable standards (see the
marking) EN 60079-0, EN 60079-11, EN 60079-15 and EN 60079-31.
For use as group I electrical apparatus M2 the apparatus shall be erected in
an enclosure that ensures a sufficient protection according to EN 60079-0
and EN 60079-1 and the degree of protection IP64.
The compliance of these requirements and the correct installation into an
enclosure or a control cabinet of the devices shall be certified by an ExNB.
2. Measures have to be taken outside of the device that the rating voltage is not
being exceeded of more than 40 % because of transient disturbances.
3. Dip-switches, binary-switches and potentiometers, connected to the module
may only be actuated when explosive atmosphere can be excluded.
4. The connecting and disconnecting of the non-intrinsically safe circuits is
only permitted during installation, for maintenance or for repair purposes.
The temporal coincidence of explosion hazardous atmosphere and
installation, maintenance resp. repair purposes shall be excluded.
This is although and in particular valid for the interfaces "Memory-Card",
"USB", "Fieldbus connection", "Configuration and programming interface",
"antenna socket", "D-Sub", "DVI-port" and the "Ethernet interface". These
